Tigers southpaw Matthew Boyd exited his start against the White Sox on Thursday with left knee tendinitis, according to the team. Boyd departed in the second inning after allowing two earned runs on three hits and a walk, and the club then replaced him with right-hander Michael Fulmer.
Until Thursday, this season had been going smoothly for Boyd, who has offered much better results than he did in 2020. After emerging as a coveted trade chip in 2019, Boyd’s value took a hit last year, during which he recorded the majors’ worst ERA (6.71) over 60 1/3 innings. He also saw his strikeout rate fall by 8.1 percent from the previous season, while his walk rate increased by almost 2 percent.
Strikeouts have been even harder to come by this year for Boyd, who has fanned batters at a lowly 17.3 percent clip. He has made up for that to some degree with a terrific 5.o percent walk rate, though, helping him to a 2.27 ERA across 35 2/3 innings. Before Thursday, Boyd hadn’t gone fewer than 5 2/3 frames in any of his starts, nor has he allowed more than three earned runs in any of his six appearances. Boyd’s fielding-independent metrics have been a mixed bag (2.95 FIP, 4.60 SIERA, 4.93 xFIP), but he ranks comfortably above average in such Statcast categories as average exit velocity against, hard-hit rate, expected weighted on-base average and expected ERA, to name a few.
It’s unclear whether Boyd will be able to build on his impressive start in the near future, as this injury could require a stint on the 10-day IL. But if Boyd’s healthy and effective leading up to the July 30 trade deadline, it’s possible he’ll resurface on the rumor mill. At 8-17, the Tigers look as if they’re well on their way to another non-contending season, and Boyd is only under club control through 2022.
